I don't think you can. What you could do is keep a table of session ids and a flag in the table to abandon it the next it is used. Then if all your pages inherit from the same custom class you could add code to check if the session needs to be closed and then call Session.Abandon().

However, I think this is poor user design. Users would be pretty upset I think to get kicked out. I think a better idea is rather than having the admin kicking someone out just don't let anymore in if they are not an admin.

I would abandon this idea, you won't get it working. For a start authentication is nothing to do with sessions, you can be authenticated with no session and vice versa. Secondly, how do you define who is logged in? The web is stateless so it has no idea who is logged in or browsing your site or has shut their browser down or gone idle.
